Using Information-Gap Tasks to Improve Reading: An Analy-sis
of Cognitive Styles
As Table 3 above indicates, with the
F value of 1.39 at
the significance level
of .71 being larger than .05, the variances between the two groups were not
significantly different. Therefore, the results of the
t-test with the assumption of
homogeneity of the variances were reported here. The results (
t =.76,
p =.44
>.05) indicate that there was no significant difference between the mean scores
of the two groups at the outset. This of course meant that since the groups were
homogeneous in their reading
before the treatment, any difference at the post-
test level could be attributed to the effect of the treatment.
Posttest
The researchers administered the reading posttest
among the two experi-
mental groups once the treatment was completed. First, however, the test had
to be piloted: the reliability of the test scores (estimated through the KR-21
procedure) gained by the participants in the pilot posttest was also .88. Table 4
below displays the descriptive statistics of this administration.
As shown, the
mean and standard deviation of the FD group were 10.79 and 2.19, respective-
ly, while those of the FI group were 10.64 and 2.39, respectively.
